The original, by Bobby Vinton. #1 in 1964 song charts. The song is about a soldier alone in a war without anyone to talk with, with no word from back home.
Victor Wood popularized “Mr. Lonely” in the Philippines. Every Filipino knows it, young or old, and they can sing it on request on their karaoke machines.
Akon created a renewed interest in the song with his modern remix. It actually features remixed voice samples from the original. Akon’s version has nothing to do with being away from at war.
